/** @file cstddef
* This is a Standard C++ Library file. You should @c #include this file
* in your programs, rather than any of the "*.h" implementation files.

* This is the C++ version of the Standard C Library header @c stddef.h,

So, the file extensions are .cpp. Would that make a huge difference if I am programming in C?

If so, can I save the files with .c in DevC++?

TY for your reply.

Some compilers make assumptions based on the extension type.

Just out of curiosity, if you are following a C tutorial, why is your program written in C++? This is as plain vanilla C++ as one can possibly write.

My only guesses at this point would mirror the above: (1) the compiler has an install problem; (2) the compiler is misconfigured; (3) you have some weird characters buried in your source file that somehow confused the compiler.

I don't know (can't) tell you what's up. I tried a different tutorial. One that seems a bit more "EDUCATIONAL". I have not done anything different, exept learned a tad more, and it has not happened again.

Hi. so this is actually a continuation from another question of mine[Here](https://www.daniweb.com/programming/software-development/threads/506795/dynamically-add-values-into-datagridview-cell-from-listbox-vb2010) but i was advised to start a new thread as the original question …

I have a 2d matrix with dimension (3, n) called A, I want to calculate the normalization and cross product of two arrays (b,z) (see the code please) for each column (for the first column, then the second one and so on).

Write a C program that should create a 10 element array of random integers (0 to 9). The program should total all of the numbers in the odd positions of the array and compare them with the total of the numbers in the even positions of the array and indicate ...
